The BlueCube™ C2 Cold Plunge Tub is the mid-tier performance system in the BlueCube lineup — engineered for serious cold therapy practitioners who demand full variable flow control, premium finish options, and the same commercial-grade construction that defines every BlueCube product.

Handcrafted in Redmond, Oregon, the C2 builds on the C1 foundation with the addition of V-RiverMode™ — a three-speed hydro-agitation system that gives clients complete control over the intensity of every session. Its refined aesthetic, curated finish options, and precision engineering position it as the ideal cold therapy instrument for luxury residential environments and high-performance daily use.
